Embodiment Construction

[0028] The main idea of ​​the present invention is to pre-set the active and standby states of the aggregated member links, dynamically detect the aggregated state during the link aggregation process, and quickly detect the failure of the working link through the connection fault management (CFM), when the aggregated link Decision making and link switching in case of failure.

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] According to an embodiment of the present invention, a method for switching aggregated links is provided.

[0031] figure 2 is a flowchart of a method for switching aggregated links according to an embodiment of the present invention, such as figure 1 As shown, the method includes (steps S202-S206):

Abstract

The invention discloses an aggregated link switching method and an aggregated link switching device. The method comprises the following steps of: configuring a main link and a standby link in a plurality of links to be aggregated; aggregating the plurality of links to be aggregated according to a link aggregation protocol and determining the working state of each link according to a link aggregation result; and detecting a connection failure management protocol for each link in the aggregated links, and judging whether link switching is performed or not according to the working state of a failed link if detecting the failed link. By the method and the device, the reliability of the links can be improved, so that the requirement of carrier-grade time switching is met.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for switching aggregation links. Background technique [0002] Link aggregation is an encapsulation technology that combines two or more data channels into one channel, which appears as a logical link with higher bandwidth. [0003] Aggregated links also provide redundancy and fault tolerance if each link of the aggregate follows a different physical path. Link aggregation can be used to improve access to public networks by aggregating modem links or digital lines. In addition, link aggregation can also be used in enterprise networks to build multi-gigabit backbone links between Gigabit Ethernet switches. [0004] refer to figure 1 , after using link aggregation, the bandwidth of the logical link increases by about (n-1) times, where n is the number of aggregated paths, and as long as one of the n links can work normally, the link can work , improving...
